I understand that the smoke generators in the HL tanks are sometimes considered little more than a silly gimmick but it is neat especially when it works to a reliable degree and so adds that extra bit of realism.

There are other hobby items that smoke one of which is an electric model locomotive. It is my understanding that these smoke units are a lot more robust and can be counted on to work over and over again. What is it about locomotive smokers that make them better?

With that being said, I really enjoy this video and the copious amounts of smoke provided by the Pershing...
